Load testing: Can load power that within the rated power, test and display stable state 3 phases voltage, current, active power, frequency, working time, etc of generator sets.
Load/unload with one key: Either by manual control, or software control, user can preset the power, then press load master button. Load bank will load according to preset power.
Control Pattern: User can choose local control and intelligent control.
Local Control: There are several power steps in panel; user can load/unload by buttons.
Intelligent Control: Through data processing software in PC, user can make automatic load, display, record and manage testing data, form curves and tables, also print them.
Control Pattern interlock: There is control pattern switch, when choose one control pattern, the other pattern is invalid to avoid the clash.
Local meter display data: Local meter can display 3 phases voltage, current, active power, frequency and so on.
